Nodular sheet of high density polyethylene (HDPE).
Product variations:
DANODREN H25 is a high density polyethylene (HDPE) brown nodular sheet. Its main use is for protection and eventual vertical drainage.


  • Drainage in accessible inverted roofs with continuous paving, placed between the thermal insulation and the paving.
  • Drainage and protection of the waterproofing of buried walls in buildings and civil works, such as cut-and-cover tunnels and subways.
  • Drainage and protection of above-ground screeds, when there is no hydrostatic pressure or the screed is above the water table.
  • Renovation of basements and underground constructions affected by damp.

Advantages & Benefits

  • In cases of renovation, an air gap is created between the damp affected wall and the new finish, allowing it to ventilate and dry.
  • Easy and quick to install.
  • Rot-proof.
  • Inalterable against chemical agents present in the soil (sulphates, chlorides, etc).
  • Provides permanent drainage.
  • Protects the wall from damp and allows water to drain, limiting its hydrostatic pressure.
  • Protects the waterproofing sheet from possible piercing caused by fill earth.
  • Resistant to breakage, impact and does not deform.

Instruction for Use

  • The support surface must be resistant, uniform, smooth, clean, dry and free from foreign bodies.r- Welding between corner and DANOPOL membrane will be achieved through hot air machine.
